Hello Tech's.
I have a Hayward H400IDL pool heater and I have a problem with the right lower connector on the printed circuit control board. The 4-wire connector must have had a poor connection and melted the connector and the plug that was soldered on to the printed circuit and fried the board around the connection.
So I am looking for a control board and the connector with wire pigtails.
Thank you, Peter Kjellberg.

BO is bypass operation fault and FS is temp.sensor failure. It is recommended that you contact a pool professional to fix this. If you are in the Phoenix Metro area you can contact me at info@wefixuglypools.com

This is the 3rd time I have had this same problem. First two times they replaced all the circuit boards under warranty. It seems as if there is an inherrent design flaw with this heater. Reseating cables on both of the last two times seemed to fix the issue. However the tech replaced the boards anyway.
